JOHN HAUG, or PHILADELPHIA, PENNSYLVANIA.

APPARATUS FOR COMPRESSING AND CHARGINGCOAL lNTO COKE-OVENS.

SPECIFICATION forming part of Letters Patent No. 747,172, dated December 15, 1903.

Application filed November 15 1902. Serial No. 181,492. (No model.)

T0 alZ whom it may concern.-

- Be it known that I, J OHN HAUG, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a newtand useful Improvement in Apparatus for Compressing and Charging Goal for the Manufacture of, Coke, of which the following isa specification.

My invention relates to improvements in apparatus for compressing and charging coal for the manufacture of coke; and it consists of means for compressing the coal placed in a compression-box and. means for removing the sides of said box from contact with the coal therein, so as to permit, the latter after beingcompressed to be easily removed from the compression-box.

It also consists of means for removing the compressed coal from the compression box and directing theformer into an oven.

It also consists of means for conveying the compression-box to any one of a series of ovens. 5 g

It further consists of means for forming the under side of the block of compressed coal with depressions to form passages.

through which the hot air, &c., in the ovens may circulate. v

Figure 1 represents a partial side elevation and partial longitudinal vertical section of my improved apparatus for'compressing and charging coal to be converted into coke. Fig. 2 represents a partial end elevation and partial transverse vertical section thereof.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings,'1 designates a truck adapted to travel on the rails 2, so that said truck may be moved along the line of ovens 3 for a purpose hereinafter described.

Pivoted to the truck 1, as at 4, (see Fig.2,)

andat proper intervals are the sides 5 of the; compression-box 6, which latter is providedf at its forward end with a gate 7, hinged, as

at 8,-(see Fig. 1,) to the truck 1 and for a purpose hereinafter described.

Journaled inthe truck rare sprocketwheels 9, around which are passedsprocket chains 10, to which is secured an endless apron 11, (see Fig. 2,) which is passed over rollers 12, journaled in the truck 1. The end-j ,less apron 11 has secured thereon a pusher sides5 on their pivots 4 when required and for a purpose hereinafter described.

Secured to a rod 18, journaled intihe upper portion of the compression-box 6, (see Fig. 2,) are bridge-bars 19, from which depend togglelevers 20, which are connected to a plate 21, for a purpose hereinafter described.

22 designates a rod provided with right and left hand screw-threads 23, whichengage screw-threaded blocks 24 in the toggle-levers 20 for the purpose of operating the latter, and consequently the presser-plate 21. The rod 22 is provided with a hand-wheel 25 for the purpose of rotating said rod.

7 One or more of the bridge-bars 19 may have projecting therefrom a lever 26, to which is connected one end of a chain, cord, &c., 27, which is wound around a drum 28 for the purpose of turning the rod 18, and consequently raising and lowering the bridge-bars 19, secured thereto, it being noted that the latter are lockedto the compression-box 6 when in the position seen in full lines in Fig. 2 by any suitable device, as at 29.

Located above the compression-box 6 are a series of bins 30, eachof which is provided with gates 31 which are opened and closed by any well-known mechanism. a The operation is as follows: The drum 28 is rotated by any suitable means and causes the chain, cord, &c., 27 to wind thereon, and thus exert a pull .upon the lever 26 in order to turn the bridge-bars 19 and cause the latter and the parts carried thereby to move out of the path of the coal discharged from a bin 30 and into the compression-box 6. The compression-box 6 is brought beneath the discharge-opening of the bin 30 and the gates 31 are opened and permit the escape of coal from said bin, and when a sufficient quantity is discharged into the compression-box 6 the gates 31 are closed to prevent the further escape of coal from the bin 30. The bridgebars 19 and the parts carried thereby are then returned into their operative positions,

. turned upon its hinge 8, so as to actas a right and left hand screw-threads 23 on the coal within the box 6 is removed and the mechanism by which the flexible apron 11 is as seen in full lines in Fig.2, after which said bridge-bars 19 are locked to the compression-box 6 by any suitable device-for inbeing'understood thatthe sides 5 of the box 6 are also returned to their normal positions, as seen in said Fig. 1, and before another stance, as indicated at 29 in Fig. 2.. The charge of coal is delivered to the box 6.

hand-wheel 25 is then rotated, whereupon the rod 22 will cause each pair of blocks 24 belonging to either of the toggle-levers 20 to move in oppositedirections-relatively to each other, it being apparent that when said rod 22 is turned in one direction it causes it? toggle-lever20 to exert a pressure on the plate f 21, and the latter then compresses the coal in the compression-box 6, and that when said rod 22 is turned in an opposite direction it causes the plate 21 to rise or move away from the cake or block of compressed coal 32 within said compression-box.

It is to be noted that when the plate 21 is compressing the coal into a cake or block 32 those portions of thecake 32 between the rollers 12 are depressed by reason of the sagging of the apron 11 at the places due to the pressure 'of the plate 21 on the coal within the box 6, it being understood that the portion of the apron 11 which is beneath and between the sprocket-wheels 9 becomes taut when the compression of the coal is being eif'ected and permits the sagging hereinbefore described to take place. When the pressure upon the driven toward the coke -oven comes into action, the top of'said flexible apron is stretched and straightened, as indicated by full lines in.Fig.1 slightly lifting the compressed block of coal 32. The position of the apron 11 when thecoal is being compressed is indicated by dotted lines in Fig. 1. After the coal within the box 6 is compressed the plate 21 is raised by rotating the rod 22 and by turning the rod'18,-and thus raising the bridge-i bars 19, secured thereto. The levers '15 are then operated and owing to the eccentrics 14 exert a pull uponthe rods 16, and the latter then cause the sides '5 of the compressionbox 6 to turn upon their pivots or hinges 4 and move away from the cake 32 in order to permit the latter to be easily removed from the com ression-box 6. The compression-box is then rought in alinementwith the door of 1 an oven 3, and the front 7 of said box is bridge between the box 6 and oven 3, as indi-- cated in dotted lines in Fig. 1. The plate or pusher 13 is then advanced toward the oven 3 by reason'of the sprocket-wheels!) and chains 10, it being understood that said sprocket-wheels may be driven by any one of the well-knownmeans now in use and that when the plate 13 is advanced it pushes the cake 32 out of the box 6 and'causes it to enter an oven 3, as seen in dotted lines in Fig. 1. When a cake 32 is placed within an oven 3,, the plate 13 isr'eturned to its normal position, a as seen in full linesin Fig. 1, and the opera It is apparent that the depressions or concave portions 33 on the under side of a cake 32, and as seen in dotted linesin Fig. 1, permit the heat in the oven 3 to pass underneath said cake '32, as. well as ever the top and arpund the sides thereof, thereby greatly improving the quality of coke produced from a cake32 of compressed coal.

Crude oil, asphalt, or other suitable substances may be used "to assist the binding of the particles of coal in a cake 32 when com pressed. r

Having thus described my invention, what I claim as new, and-desire tosecure by'Letters Patent, is

for compressing the coal and means for forming depressions'on the lower side of the cake of compressed coal. 7
